A selection of the best technical images from Abu Dhabi courtesy of Sutton Images

Above: Taken from Bottas' instragram feed we can see that Williams trialled the PCU-8D display, which can provide more information

Above: Mercedes (Nico Rosberg) with a pitot tube array placed behind the left front tyre, assessing the tyre wake of the 2015 construction of Pirelli tyres

Above: Williams run three centralised pitot tube arrays to measure how the flow moves over the car, the most forward array measures flow around the nosecone (lower right circle), whilst above the roll hoop and mounted on the DRS actuator two more pitot tubes assess how the flow is disturbed.

Above: Force India with several test elements on the car, circled is a row of pitot tubes mounted above the leading edge of the rear wing endplate.

Above: Force India with a pitot tube array mounted behind the diffuser/left rear wheel assessing how the 2015 tyre construction affects the tyre wake and how that impinges on diffuser performance.

Above: Ferrari with numerous pitot tube arrays mounted on the F14T to assess tyre wake from the front left of the car.

Above: Toro Rosso with a pitot tube array mounted behind the left front tyre, note that not all parts of the array have pitots fixed in them.

Above: Red Bull Racing with numerous test methods being used together, note the cameras placed in the wing mirrors assessing the front tyres, whilst pitot tube arrays are mounted behind the front left tyre and above the rear wing endplate.

Above: Toro Rosso with a pitot tube array measuring the performance of the diffuser

Above: Sauber using a pitot tube array behind the left front tyre to assess its wake, the array is able to move vertically in order that smaller sections are tested at once.

Above: Force India VJM07 circled is a camera mounted within the wing mirror looking at and assessing the front right tyre

Above: Force India measuring the airflow at the leading edge of the rear wing endplate

Above: McLaren MP4-29H 1x1 didn't turn too many laps during the test, nothing to be desperately worried about though as that is what these sort of tests are for and allowed the team time to understand any installation problems with the Honda PU. As we can see in the circle the team were taking no chances when it came to cooling adding three cooling gills in the side of the sidepod. These are not legal so couldn't be run at a race day (no holes/slots in this region allowed by regulation).

Above: Although we noted the additional cooling ducts present in the left hand sidepod as we can see they aren't present on the right side.

Above: Force India VJM07 note the pitot tube (may be a kiel probe) mounted on the long stem above the airbox

Above: Ferrari F14T circled is what appears to be a ride height sensor (much like we'd normally see mounted under the chassis) likely analysing (and using the forward one as a benchmark) to understand how the rake of the car is affecting downforce (especially with the 2015 tyres on offer at the test). The other smaller circles show pitot tubes mounted on the car measuring airflow.

Above: Ferrari F14T another angle showing the sensor mentioned above, whilst on the other side of the car the team have added a pitot tube array to assess the tyre wake and how it impinges on diffuser performance

Above: Lotus E22: An item we have seen the team use before (circled) looks across at the front tyres sidewall allowing the team to understand deformation

Above: Red Bull RB10 - Fans used to cool the Reanult PU

Above: Ferrari F14T complex pitot tube array surrounds the front left tyre measuring airflow close to the tyres surface and also the flow moving around the front wheel

Above: Williams FW36 - Already mentioned above but a close up of the pitot tube mounted above the DRS actuator pod

Above: Ferrari spying on the opposition, using a thermal image camera to assess other teams cars

Man those are awesome shots, thank you! too long but I'll make due of what I can view. Are you sutton or sutton allows you to take his images? I would like to learn from him if he does as I should be taking some photos of it this year

Whilst I'm trying to keep atop of the blog you may have noticed of late that there is less content appearing. For those of you that haven't realised, most of my work has now been moved over to Motorsport.com where I'm working with Giorgio Piola.

I'm still doing the technical image gallery for each GP with the continued support of friend of the site Sutton Images. However, as always my time is limited and so this might not be updated as quickly as it once was, so keep checking back.

As some of you may have found out already I'm also working with the Missed Apex crew on their podcast from time-to-time, either doing race reviews or dedicated 'Tech Time' shows.

I've embedded the latest version of the podcast below and will update this a frequently as I appear. However, please head over to Itunes if you want it to appear in your player when episodes are available. The show is great to work on and has a great lineup of 'regulars' but has also enticed some bigger names recently too, with Will Buxton and Bradley Philpot on shows during the summer break.
